‎First printing of the paper in which - after being persuated by a committee lead by Arago to make further experiments - Poiseuille generalized the law named after him, first announced in 1840. He studied experimentally the flow of different liquids through capillary tubes, and found the law named after him, that relates the flow to the pressure, the diameter and the lenght of the tube and to the viscosity of the liquid. Poiseuille's investigations are fundamental in blood viscosimetry. ""Poiseuille's work represents a major advance in blood pressure measurements""(Gedeon p. 189).""Poiseuille’s paper (the 1840-paper) was reviewed by a committee consisting of Arago, Piobert, and Regnault. They persuaded him to make further experiments with ether and mercury, and these investigations were published in 1847 (the paper offered). He found that ether yielded the same law as distilled water, whereas mercury obeyed a different law. In 1870 Emil Gabriel Warburg found that mercury obeys the Poiseuille law, except for certain anomalies caused by amalgamation in metal tubes.""(DSB). The paper was also printed at the same time in ""Comptes Rendues"".The volume contains other notable papers by August Laurent, Matteucci, Bravais, Senarmont ""Mémoire sur la Conductibilité des Substances cristallisées pour la Chaleur"", pp. 457-470.‎
